Goodman GKS90905DX Control Board
Your furnace or AC will not operate lest the main control board is hooked up and is correctly configured. The control board is created to control the gas valve, the igniter, the flame sensor as well as the blower all in one unit. You must do some research when choosing a control board because of the diversity of HVAC systems. A matching board should have part numbers that match both the brand and model of the unit in question.
Subtle hints your main board should be replaced
- Air conditioning or heating system refuses to initialize whatsoever
- The system board has to be reset many times a day in order to continue running
- There seems to be a fault code displayed somewhere on the board
